Tradeoff Studies on Total Serviceability Evaluation for Disaster Monitoring by Satellites

Abstract

This paper demonstrates the applicability of serviceability function to the studies of satellite constellation tradeoffs for detecting damaged area distribution in the emergency response after disaster eruption. The example studies indicate that constellations of synthetic aperture radar (SAR) satellites with different local sun time orbits can be effective for early response following a disaster. This study also proposes the introduction of visibility and interpretability criteria for disaster monitoring, beginning with the addition of necessary criteria for use in the emergency response phase. Here, image-based products that combine the change detection by SAR and compensational use of optical imagery, social database and matured operators are proposed as possible candidates for employment during this phase, which are to be evaluated by the criteria.
